Leantime 3.6.2 contains a server-side request forgery and local file inclusion vulnerability that allows authenticated attackers to read internal resources by passing unsanitized user-supplied filenames to file_get_contents() in the Blueprints::import() method without path validation. Attackers can submit crafted filenames containing URL wrappers or path traversal sequences through the JSON-RPC API endpoint to access cloud metadata services or read arbitrary files from the server filesystem.
